Other Preventive Measures

SRP: The scientific literature for the use of contact lenses by industrial workers is inconsistent. The benefits or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.
SRP: Contaminated protective clothing should be segregated in a manner such that there is no direct personal contact by personnel who handle, dispose, or clean the clothing. The completeness of the cleaning procedures should be considered before the decontaminated protective clothing is returned for reuse by the workers. Contaminated clothing should not be taken home at the end of shift, but should remain at employee's place of work for cleaning.
Respirators may be used when engineering and work practice controls are not technically feasible, when such controls are in the process of being installed, or when they fail and need to be supplemented. Respirators may also be used for operations which require entry into tanks or closed vessels, and in emergency situations. ... Clothing wet with liquid acetonitrile should be placed in closed containers for storage until it can be discarded or until provision is made for the removal of acetonitrile from the clothing. If the clothing is to be laundered or otherwise cleaned to remove the acetonitrile, the person performing the operation should be informed of acetonitrile's hazardous properties. Any clothing which becomes wet with or non-impervious clothing which becomes contaminated with acetonitrile should be removed immediately and not reworn until the acetonitrile is removed from the clothing. ... Skin that becomes contaminated with acetonitrile should be immediately washed or showered to remove any acetonitrile.
If material not on fire and not involved in fire: Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Attempt to stop leak if without undue personnel hazard. Use water spray to disperse vapors and dilute standing pools of liquid.
Personnel protection: Avoid breathing vapors. Keep upwind. ... Avoid bodily contact with the material. ... Do not handle broken packages unless wearing appropriate personal protective equipment. Wash away any material which may have contacted the body with copious amounts of water or soap and water. If contact with the material anticipated, wear appropriate chemical protective clothing.
Evacuation: If material leaking (not on fire) consider evacuation from downwind area based on amount of material spilled, location and weather conditions.
The worker should immediately wash the skin when it becomes contaminated.
Avoid contact with skin and eyes. Avoid inhalation of vapor or mist. Use explosion-proof equipment. Keep away from sources of ignition - No smoking. Take measures to prevent the build up of electrostatic charge.
Work clothing that becomes wet should be immediately removed due to its flammability hazard (i.e., for liquids with a flash point. <100 deg F).
Prior to working with this chemical you should be trained on its proper handling and storage. Before entering a confined space where acetonitrile may be present, check to make sure that an explosive concentration does not exist. ... Sources of ignition such as smoking and open flames are prohibited where this chemical is used, handled, or stored in a manner that could create a potential fire or explosion hazard.
If employees are expected to fight fires, they must be trained and equipped in OSHA 1910.156.
